In an expedition to the court of Mark, king of Cornwall and England, Riwalin, king in the land of the Parmenians, had become acquainted and subsequently passionately in love with Mark’s beautiful sister, Blancheflure. Later, as he was assisting Mark in a campaign, Riwalin became mortally wounded and was carried to Tintajole. Blancheflure, disguised as a beggar maid, hastened to his sickbed and saved Mark’s life through her devoted love. The lovers then fled together to his native land and Blancheflure was proclaimed as his consort. However, Morgan attacked Riwalin’s country and, the king entrusted the pregnant Blancheflure to his faithful retainer Rual. Rual placed the queen for safekeeping in the castle of Kaneel. Here she gave birth to a son and died as her husband fell in the battle against Morgan.
In order to protect the king’s son from Morgan’s pursuits, Rual spread the rumor that the infant had been born dead. The boy was named Tristan because he had been conceived and born in sorrow. Under the care of Rual and his wife, Tristan grew up strong in body and mind until his fourteenth year, when he was kidnapped by Norwegian merchants, who then put him ashore in Cornwall because they feared the wrath of the gods. Here the boy was found by the soldiers of King Mark, who was so pleased with the brave and handsome youth that he made him his master of the chase.
Meanwhile, the faithful Rual set forth to look for his abducted foster son. Disguising himself as a beggar, Rual found Tristan in found at last in Cornwall. Rual revealed the story of Tristan’s birth to the king who was delighted to see in him the son of his beloved sister and raised him to the rank of knight. To avenge his father, Tristan proceeded with Rual to Parmenia, vanquished Morgan the usurper, and gave the country to Rual as the liege while he himself returned to his uncle Mark.
In the service of Mark, Tristan killed Morald, the bridegroom of Isolde. Being severly wounded, Tristan was saved by Isolde herself. Tristan then asked her hand in marriage on behalf of his uncle Mark. When he fulfilled the condition of killing a dragon, Isolde reluctantly accompanied Tristan to Cornwall. On the journey they unwittingly drank a disastrous love potion which bound them together in frenzied passion.
On Isolde’s wedding night with Mark, Isolde had her faithful maid Brangäne represent her and sacrifices her virginity to the king. Next followed the banishment of Tristan, Tristan’s attempts to regain his beloved, although he had meanwhile married another Isolde (“Isolde the White Hand,” of Brittany) who resembled his beloved “Isolde the Fair.” At last Tristan was again severely wounded. Only this time his beloved Isolde arrived too late to save him.
A plainer version of the Tristan saga is found in the fairy tale “The True Bride,” quoted by Riklin from Rittershaus. In this story, the childless royal pair were much less affectionate. The king threatened to kill his wife unless she bears a child by the time of his return from his sea voyage. Seeing that sea voyages are long and the king was, apparently, rather stupid. The queen was secretly brought to him during his journey, by his zealous maid-servant, as the fairest of three promenading ladies, and the king took her into his tent without recognizing her. After sleeping with the king, the queen returned home without having been discovered. She then gave birth to a daughter, Isol, and died.
When she was older, Isol found a most beautiful little boy in a box by the seaside. The name of the boy was Tristram. Isol raised him and became engaged to him. The subsequent story, which contains the motif of the true bride, is noteworthy for present purposes only in so far as here again occurs the drink of oblivion, and two Isoldes. The king’s second wife gave a potion to Tristram which caused him to completely forget his Isol, leading him to marry Isota. However, he ultimately discovered the deception and became united with his Isol.
